HW8 Visualizations

This is my submission for my homework 8 assignment.

1. Visualization Num. 1

For the first visualization, I created a bar chart to show the building usage across the different congressional districts. For the bars, they each represent a congressional district, and the height of the bar shows the count of buildings in that district. I put the congressional district on the x-axis and the count of buildings on the y-axis. Additionally, I applied a color scheme to differentiate between different usage descriptions, allowing readers to easily identify the dominant types of buildings in each district. In terms of data transformations, I preprocessed the dataset by filtering out any rows with missing values and grouped the data by congressional district and usage description to obtain the count of buildings for each category.

2. Visualization Num. 2

For the second visualization, I created an interactive scatter plot that shows the relationship between the year a building was acquired and its square footage. Each point on the plot represents a building, with the x-axis representing the year acquired and the y-axis representing the square footage. I used a ordering color scheme to represent the usage description, helping readers to visually identify the different types of buildings based on their colors.
